Isomo rya 1: Izayi 60,1-6
Haguruka, ubengerane Yeruzalemu! Kuko urumuri rwawe ari nguru, kandi ikuzo ry’Uhoraho rikaba rikurasiyeho. Nyamara dore umwijima utwikiriye isi, n’icuraburindi ribundikiye amahanga; ariko wowe, Uhoraho azakurasiraho, n’ikuzo rye rikubengeraneho. Amahanga azagana urumuri rwawe, abami basange umucyo ukurasiyeho. Kebuka impande zose, maze witegereze: dore bose barakoranye, baje bakugana, abahungu bawe baturutse iyo bigwa, n’abakobwa bawe baje bahagatiwe. Nuko uzabirebe maze unezerwe, umutima wawe wisimbize, utaratswe n’ibyishimo, kuko ari wowe bazazanira ubukire bwo hakurya y’inyanja, n’umutungo w’amahanga ukazataha iwawe. Amashyo y’ingamiya azakuzuranaho, ingamiya zikiri nto z’i Madiyani n’i Eyifa; abantu bose b’i Saba bazaza, bikoreye zahabu n’ububani, kandi baze baririmba ibisingizo by’Uhoraho.

R/ Nyagasani, abami bose bazapfukama imbere yawe, amahanga yose akuyoboke.
Mana, umwami umwegurire ubucamanza bwawe,
uwo mwana w’umwami umutoze ubutabera bwawe;
acire umuryango wawe imanza ziboneye,
kandi arengere n’ingorwa zawe.
Mu gihe cye ubutabera buzasagamba,
n’amahoro asesure mu mezi atabarika.
Azategeka kuva ku nyanja kugera ku yindi,
avane ku Ruzi ageze ku mipaka y’isi.
Abami b’i Tarishishi n’ab’ibirwa bazamutura,
abami b’i Seba n’ab’i Saba bamurabukire.
Abami bose bazapfukama imbere ye,
amahanga yose amuyoboke.
Azarokora ingorwa zitakamba,
n’indushyi zitagira kirengera.
Azagirira ibambe ingorwa n’utishoboye,
aramire ubuzima bwabo.

Twabonye inyenyeri ye mu burasirazuba, none tuje kumuramya.» Umwami Herodi abyumvise, akuka umutima, we na Yeruzalemu yose. Akoranya abatware bose b’abaherezabitambo n’abigishamategekob’umuryango, abasiganuza aho Kristu yagombaga kuzavukira.

Nuko ya nyenyeri bari baboneye mu burasirazuba ibajya imbere irinda igera hejuru y’aho umwana yari ari, irahahagarara. Ngo babone inyenyeri barishima cyane.

Cyakora baburirwa mu nzozi kudasubira kwa Herodi, banyura indi nzira basubira mu gihugu cyabo.
